2023
Saccharomyces cerevisiae is a species of yeast that is an extremely valuable model organism. Importantly, S. cerevisiae is a unicellular eukaryote that undergoes many of the same biological processes as humans. This video provides an introduction to the yeast cell cycle, and explains how S. cerevisiae reproduces both asexually and sexually Yeast reproduce asexually through a process known as budding. In contrast, yeast sometimes participate in sexual reproduction, which is important because...

2025
In this video, we demonstrate the luciferase assay to quantify the growth of the intracellular pathogen Toxoplasma gondii. Utilizing a strain of Toxoplasma that expresses luciferase enzyme after infecting the host cells, the luciferase activity is detected in the infected cell culture to determine the successful reproduction of the parasite.

Drosophila Development and Reproduction

2023
One of the many reasons that make Drosophila an extremely valuable organism is that the molecular, cellular, and genetic foundations of development are highly conserved between flies and higher eukaryotes such as humans. Drosophila progress through several developmental stages in a process known as the life cycle and each stage provides a unique platform for developmental research. This video introduces each stage of the Drosophila life cycle and details the physical characteristics and major...

FAQs
These processes are coordinated rather than independent. Genetic information supplies the biological basis for regulated changes, cellular signaling helps control when and how those changes occur, and environmental conditions can influence the outcome. Considering all three factors together helps explain why reproduction and growth vary across organisms and why biology studies them as linked processes.
The two pathways differ in how genetic material is handled. Sexual reproduction includes meiosis, which generates gametes, followed by fertilization, which combines genetic material to begin formation of a new organism. Asexual reproduction represents a contrasting reproductive mechanism that does not use this meiosis-and-fertilization sequence, making the distinction useful when comparing life cycles.
Growth reflects several coordinated cellular changes rather than size increase alone. Cells divide, enlarge, and differentiate, while nutrients support these activities. Regulation is important because growth depends on interactions among cellular processes, genetic information, signaling, and environmental conditions. This framework helps biologists distinguish developmental change from enlargement without accompanying cellular specialization.
Meiosis and fertilization occupy complementary positions in sexual reproduction. Meiosis generates the gametes, while fertilization combines their genetic material to form the starting point of a new organism. Studying these stages allows biologists to connect cellular events with inheritance and development, rather than treating reproduction as a single undivided event.
Biologists use the topic to connect events in individual organisms with changes across generations. Reproductive mechanisms help explain how offspring arise, while growth and development show how organisms change after formation. At the population level, reproduction contributes to continuation and change across generations, making the subject relevant to inheritance and population biology.
Applications include breeding, conservation, regenerative biology, and reproductive health. In each area, understanding reproductive or growth processes provides a scientific basis for a different goal: producing organisms, supporting populations, studying biological restoration, or examining reproductive conditions. These applications show how the topic extends from basic biology to practical research and health-related contexts.
